Obama will match Roosevelt's record four swearing-ins

He's limited to two terms — but President Obama is set to match President Franklin D. Roosevelt's record of four swearing-ins.

The first pair of swearing-ins were the result of an accident — the second pair are the result of a quirk of history, the Associated Press reports:

He's planning a private oath at the White House on Jan. 20, when the Constitution requires that his second term begin. But since presidential inaugurations are not traditionally on Sundays, his public swearing-in is scheduled Jan. 21.

In 2009, Obama had a do-over of his oath the day after Supreme Court Chief Justice John Roberts accidentally mixed up the words in the public ceremony.
